Progress on manufacturing of zirconia film for fuel cells

固体氧化物燃料电池(SOFC)具有高效率、低污染等优点,氧化钇稳定氧化锆(YSZ)是目前用于SOFC的最成功的电解质材料,为了减小高温运行带来的困难,应用中需将YSZ制成薄膜。综述了制备YSZ 薄膜的各种方法,其中包括化学气相沉积(CVD)、电化学气相沉积(EVD)、溶胶-凝胶法(Sol-gel)和喷雾热解法等化学方法;物理气相沉积技术(PVD)和喷涂技术等物理方法;以及电泳沉积法(EPD)、注浆成型法和离心浇铸法等陶瓷成型方法,介绍了近年来采用上述方法制备的YSZ膜的性能及其用于SOFC电池研究取得的实验结果,最后评述了这些方法各自的特点。

Solid oxide fuel cells (SOFCs) have many advantages, such as high efficiency and low pollution. Yttria stabilized zirconia (YSZ) is the most successful electrolyte material for SOFC. However, to overcome the difficulties with high operating temperature, YSZ should be prepared to be a thin film for application. The manufacturing methods of electrolyte YSZ film were reviewed. These methods included: chemical ones, such as chemical vapor deposition(CVD), electrochemical vapor deposition (EVD), sol-gel and spray pyrolysis, physical ones, for example, physical vapor deposition (PVD) and thermal spray technology, and ceramic powder processes, e.g. electrophoretic deposition (EPD),slip casting and centrifugal casting. The properties of YSZ films made by above-mentioned methods and the experimental results of fuel cells made from these films were introduced. The characteristics of each method were reviewed at the same time.
